I have just taken delivery of the Synology DS918+ and 2 * 8TB WD Red Pro's.

I have failed to install the DSM to either either 8TB drive individually, when in slot 1 and the Synology Setup routine is giving me a Failed to Format Drive (35), when it try's to put the initial DSM on.

I slotted into slot 1 a 2 TB WD RED, which I had spare, and that installed the DSM correctly.

I then slotted in the 2 8 TBs back into slots 2 & 3, neither drives were visible in HDD/SDD area of storage manager.

I took one of the 8TB's and slotted it into a spare bay on my DS2413+, and that didn't see it.

Question 1Would the 8TB WD RED Pro, be visible in the DS2413+ (I did check the compatibility list and it did say yes).

Question 2Experience would say that 2 8 TBs borked?

Extra thing, is that the 2 8 TBs drives are really humming in the DS918+ (and in the 2413+), I mean really humming/vibrating. I hadn't expect the difference in noise to be so significant, between the Red Pro (7200) and the Red (5400)

2 drives shipped at the same time could be borked, this would disappoint but not shock me. drive infant mortality related to poor shipping is real. maybe try them in a USB case on your PC before you ship them back for replacement?

When you are using the Synology Assistant to install the DSM, does it matter if it's very upto date ?

So does it need to know about WD RED Pro's 8TBs in it's list of valid drives? I am wondering if my Synology assistant was a year or so out of date, would it know about them, does it even need to know about them?

It saw the disks and knew there were 2 installed on the DSM, and it saw the Synology.

I am looking at buying the DS918+ next week. Any feedback on WD RED disk clicking noise using the DS918+?

I have recently bought the QNAP TS-453B and 2 WD RED 8 TB drives.I have tested both drives using the utility program from WD and they test OK. I dont hear any real noise from them spinning.However the clicking noise from the read/write process it high, both when connected to the NAS and when connected to laptop via USB mount.

The noise is so annoying that I won't be able to have it connected directly to my TV, not even in a cupboard under the TV. I don't really see the benefit of paying the extra compared to the DS918+ then!

My older WD RED 8 TB drive which I had in an WD EX4100 NAS has the same clicking noise - this setup though wasn't noisy at all compared to the QNAP setup.Can it be because of the plastic construction of the QNAP? The DS918+ is also plastic, right?
